To 11.2. 10710771, it may concern.-

Be it known that I,\VILLIAM L. D. WRIGHT, a citizen of the United States, and a resident of the borough of Brooklyn, in the city and State of New York, have invented a new and useful Improvement in Traveling AdvertisingDcvices, of which the following is a specification.

My invention relates to an improvement in iraveli ug advertising devices, and has for one object to provide a device in which two endless carrying-chains are driven in some suitable manner, the said ca rrying-chains having reinovably secured thereto any number of changeable advertising-sheets,the said sheets being secured to the chains by devices removable from the sheets and the chains, so that the sheets may be attached to the chains at any desired point or points.

A further object is to provide a very simple and effective means for supporting the chains both verticallyand laterally, whereby the device maybe tilted to any desired angle without interfering with the movement of the chains, and, furthermore, permitting the chains to run around their sprockets with sufficient slack to enable the chains to be driven with every slight amount of power.

A practical embodiment of myinventiou is represented in the accompanying drawings, in which Figure 1 represents a frontview of my improved traveling advertising device, portions of the samebeing broken away to more clearly illustrate thef'interior structure of the device. Fig.2 is at'ransverse horizontal section taken in the plane of'the line 2 2 of Fig. 1. Fig. 3 is a transverse vertical section taken in the plane of the line 3 3 of Fig. 1. Fig. 4 is a considerably-enlarged detail vertical crosssection through the upper and lower portions of the device. Fig. 5 is a detail view, partially in section, showing the manner of supporting the upper and lower chains vertically and laterally. Fig. 6 is another detail view showing the manner of securing the adver-' tising-sheet to the upper and lower chains by the devices which are separate from'the said sheet and chains, and Fi 7 is a dot-ail view of the pin portion of the removable device for securing the sheet to the chain.

A designates a frame or casing which may are driven.

be made in sizes to suit difierent require The front a of the casing A is preferably made of transparent glass, so as to protect the parts of the device within the easing, but at the same time exhibit the advcrtising-sheets therethrou'gh. A vertically-disposed drive-shaft B is mounted in the top a and bottom a of the casing, near one end thereof, which shaft is provided with ,upper and lower sprockets b I), located near the top and bottom of the casing. This shaft'may be driven at the required speed from any source of power, that shown herein being a motor, represented conventionally at (J, located within the casingAand having a geared connection with the said shaft B. A verticallydisposed shaft D is mounted in the top a and bottom a of the casing, near the other end thereof, which shaft is provided with upper and lower sprockets d (1', located near the top and bottom of the casing. An upperendloss sprocket. -chain E is caused to travel around the sprockets b and d, and a lower endless sprocket-chain E is caused to travel around the sprocket-s b (1'. These sprocketchains are preferably composed of a series of double links e of general. U-shaped form, the

bottom 6' of each link being engaged by two eyes e e at the ends of the branches of the next succeeding link. These eyes e e are of sufiicient size to also permit the insertion therethrough of a small pin or rod.

The top a. of the casing is provided near its front and rear on its interior with grooves a. a, within which the upper endless chain E is caused to travel. The bottom a of the easing is provided on its interior near the front and rear with similar grooves a a in which the lower'endless chain E travels.

The chains E E are supported vertically I and laterally in the following manner: A small rod F extends through the eyes e e in one of the links of the upperchain and through the eyes e e in the correspondinglink of the lower chain. This rod l is provided at its lower end with a small traction-wheel or caster f, which travels along the bottom of the grooves a 0, within the casing as thechains shoulder f. just beneath the upper chain E 'for supporting the upper chain in a vertical The rod F is provided wit-h a the lower chain E for supporting the loweriparts. Furthermore, by, the use "of the required number ofsupportingrods F, I -'amchain in a verticatdirection. 'Thej'sho'ulder f is preferably formed by doubling therod. F upon itself, and the shoulder f is formed by a washer on the said rods An afitifrictionroller f is mounted on the vertical portion of the rod F, between the shoulder f and a second shoulder f on therod, which antifriction-roller travels along in engagement with one or-the other of the walls of the grooves a a as the case may be, for supporting the lower chain in a lateral direction. A second antifrietion-roller f is mounted upon the upper end of the rod F above the upper chain E, which; roller iscaused toengage either the inner or outer "walls, as the case may be, of

the-grooves a. d for supporting the upper chain E in a lateral direction.

The tractiomwhe'el f is arranged to trail by bending the lower portion of the rod F at an angle to its main portion. By thus causing the traction-wheel to trail I am enabled .to keep the double portion f of the rod F,which supports the upper chain, in a direction parallel with thechain, so as to prevent any u ndue friction as the chains pass around the sprockets on the shafts B and D.

The advertising sheet or sheets may be secured to the upper and lower chains in the following manner: A pin G is provided at one end with a double hook, the inner hook portion-g being adapted to exert the pull onthe sheet when the pin has been passed therethrough. The pin G is made in different lengths, so as to reach from the top and bottom of dilferent-sized sheets to thempper and lower chains. The pin is of a sufiicient length to pass through the eyes 6 e in one of the links of the chain and project a slight distance above the chain. A retaining-band g of some suitable material-such, for instance, as rubber-'is caused to engage theouter por-' 'tion g of the double hook and also the end of the pin which projects through the chain, thus preventing unintentional removal of the pin from the chain. These devices for secur- ,,ingthe sheets tothe chains may be attached The idler-shaft D tothe sheets at any desired points for holding the sheets securely without wrinkling the same.

' I provide the drive-shaft B with a. roller 1), extending between the upper and lower sprockets 6?), of substantiallythe same diamva roller (1 The device whenronstru'cted as above set forth-maybe tilted to any required is withoutinterfering in anyrespect withthe proper operation of the chainsiand theinattached 1' enabled to provide a'device of great length and one in which the chains may be driven with the least amount of friction, for-the reason that the chains do not have'to be drawn taut to keep them in position. Furthermore, by my-improved devices for securin'gthe'advertising-sheets to the chains the sheets may.

be of any required shape or size and yet be properly carried by the'chains. A I It is evident that changes might be resorted to in the form and arrangement of the several parts without departing from the spirit and scope of my invention. Hence I do not wish to limit myself strictly to the structure herein set forth; but What-I claim is--.
